6 days late still BFN

Katie

OK so TTC for #2 and we did the dance at the right times. Now CD37 DPO15 and still no positive test. My nipples are sore, my back aches, I hate the taste of alcohol and I have loads of CM all things that happened when I was pregnant the first time BUT when I tested for my daughter I got a positive 2 days before my period. I am now nearly a week late with no signs of my period and so confused!?!?!

Anyone else gone through this?

Any advice ?
